diesel pump tuning on 113hp 300GD six cylinder
I have read somewhere that someone with this engine changed the dieselpump and gained 20hp!
Unfortunatly it was in an ad for his G wich is now removed, so I can no longer ask him :cry:
Is there anyone who heard about this? Where can I find more info?
This would really be worth it I think!!!
thx,
G
Sorry i cannot help, but....do a 'google' all turns up there. good luck
Next time if you have to pass an emissions test just put some good old cooking oil into the tank. It will be lower than a brand new Saab.
The Finnish lot can do this.. but it cost £1000 at least;

Go and search under diesels on www.pointedthree.com e.g.

My notes on this say <> not sure where that is from!

.. which is applicable to all tuning.. i.e you want an EGT (exhaust gas temperature) gauge and then tweak timing and volume settings to get more power while monitoring temperatures and smoke.
A turbo tunes well but a n/a engine will struggle to make the 20% more power you are talking about TBH .. and you would more easily make this extra power by adding an aftermarket turbo kit which is still available... or find a 617a turbo diesel version of this engine as fitted to 300TD estates .. but all these are £1000 options.. but I guess you should be able to up the fuel delivery to run more smoke and get the power..

Enjoy!
I'm afraid there is "no such thing as a free lunch". You want more power you will reduce the life of the parts; guess the question is how much. With an old 617 they are proven 500k mile engines.. so if adding an aftermarket turbo will maybe make it a 350k mile engine.. but at my rate of miles (3k miles/year) I suspect oil will run out first for me!
The issue would be getting a cast exhaust manifold that put the turbo in the right place relative to everything else.. and how the local emissions police regard this conversion. Fuelling increase is just same as other mechanical injection pumps with aftermarket turbo.. not nice but it does give a little lift of horses.. of course you really want to intercool it to make it right.. and add a turbo injection pump.. and after all that it could be tuned to be a reliable engine. But never expect any modified engine to be as reliable as a factory tested one. :cry:
Now that I driven it for a couple of thousand miles....
-I am getting used to the slow but determined nature of the truck...
-It uses too little diesel....13 liters/100km
well, it still uses a lot, but it uses less than the MB manual says. That has not happened to any car I own, so I suspect that they adjusted the pump to a poor mixture in order to pass emissions there.
